  • Why is natural coagulant a promising technology in water and wastewater treatment?
  • The utilization of natural coagulant is a promising technology in water and wastewater treatment due to its environmentally friendly and its reliable treatment performance, which is comparable with that of the chemical coagulant.
  • What coagulants are used in wastewater treatment?
  • Well-established commercial tannin-based coagulants such as Tanfloc, Silvafloc and Acquapol have been applied in many wastewater treatment studies over the past decades. A Tanfloc dosage lower than 10 mg/L was found to eliminate almost all suspended matter in a river water sample.
  • Can natural coagulants be used in water treatment?
  • The transition from chemical to natural coagulants can be an alternative solution to minimize the environmental pollution and health risks caused by the use of chemical coagulants [ 9, 10 ]. The use of natural coagulants in water treatment has become imperative due to its biodegradable and environment-friendly nature.
  • What chemicals are used for coagulation treatment?
  • At the beginning, various inorganic chemicals were used for coagulation treatment. For example, alum (aluminum sulfate) is the most commonly used coagulant for wastewater treatment throughout the world [ 4, 7, 8 ]. It was reported that about 90 % dye removal was achieved with alum dosage.
